A question was asked that how can you calculate a no of leap year in 100 years but answers provided does not give a clear solution to the question. Please, tell me how can I know that 100 is the beginning of the year? Thanks.

In 400 consecutive years, there are 97 leap years. Hence in 400 consecutive years, February has the 29th day 97 times. How was 97 leap year gotten?

Odd days -consider no of weeks in 15 days=15/7=2 week plus1additional day
This additional day is an odd day.
To solve given Q : ordinary yr =52
weeks plus 1 odd day=365 days
Leap yr=52 plus 2 odd days=366 days
2006 ordinary-1 odd
2007 ordinary-1 odd
2008 (leap bcoz divided by 4)-2 odd
2009 ordinary-1 odd
2010 ordinary-1 odd
Total odd days=1+1+2+1+1=6.

Thank you @Pavitra for your concept. And the only thing I found this for leap year. Especially if we calculate the month of Feb in any leap year. We have to use (answer-1) as the real answer. If I am wrong please let me know.
